    Abstract:
    BACKGROUND: Invasive fungal infections (IFI) are severe infectious complications frequently observed in patients with hematological disorders. The aims of this study were to analyse the characteristics of this particular type of infection in a large series of a single institution and to determine the factors associated with the outcome and therapeutic response. PATIENTS AND METHODS: This study reviews the clinical and microbiological features of 155 IFI occurred among 144 patients with hematologic disorders throughout a period of 17 years in a single institution. RESULTS: In 118 cases (82%) the diagnosis was acute leukemia. The main risk factors for developing IFI included a persistent and profound granulocytopenia, the use of broad-spectrum antibacterial agents, indwelling central venous catheters and the damage of normal host barriers following intensive cytotoxic chemotherapy. Candida (65 cases [44%]) and Aspergillus (38 cases [26%]) species were the most common fungal species isolated. An increasing number of IFI were caused by fungi previously considered as contaminants or harmless colonizers. The outcome of IFI was favourable in 78 cases (50%). The most important prognostic factors for the outcome of the IFI were the phase of cytotoxic chemotherapy (p = 0.005), the response of the underlying disease to the cytotoxic chemotherapy (p < 0.00001), and the recovery of neutropenia during the infection course (p < 0.00001). An earlier use of empirical antifungal therapy was also associated with a better outcome. CONCLUSIONS: In spite of earlier treatment and regardless the development of new antifungal agents, the prognosis of IFI in patients with hematological malignancies remains poor. The use of hematopoietic growth factors, through their impact in the duration and severity of neutropenia, may prove valuable the management of IFI in this setting.
